Plate Techtonics

1. Transform boundaries

1.1. slide or grind past each other along transform faults

1.1.1. example: California's San Andreas Fault

2. Divergent boundaries

2.1. when two plates slide apart from each other

2.1.1. example: Mid-Atlantic Ridge and Africa's Great Rift Vall

3. Convergent boundaries

3.1. two plates slide towards each other forming either a subduction zone or a continental collision

3.1.1. example: causes deep ocean trences and mountains
